hereby declare the following clear,

and exact description of art to which it the same.

of tion with pipe is applicable to rings for other purposes.

In th shown an lected 'by invention relates to the manufacture 3 wroughtmetal rings for use in conneccoupllngs, but the invention f mefor;

clamps for bell and spigot pipes, but the for this purpose;

In the said drawings, Figure 1 represents a side elevation "partly insection of a Matheson joint provided with a clamp, the clamping ring andI Fig/2 is a partial sec. tiona-l view of the same drawn to a largerscale. -Fig. 3 isv apsectional view of the clamping ring ont-he'samescale as Fig. 2,

portions of the ring being broken away. Figs. 4 to 8 inclusive aredetail sectional views of modified forms of my improved The bell andspigot joint of which the well known Matheso'n in Figs. 1 and 2, is anexample, comprises two pipe sections'l, 1, each provided at one end withan enlarged portion or bell 2. to receive the section, {the space withinthe bell surrounding the spigot being'filled with a non-elastic packingl, such as lead, cement or the like. In order to insure that thesejoints will notworkloose and leak, it is customary to apply'tof the' aclamp which comprises an'elastic' packingring usually of rubber 5tolsurround the spigot 3 and engage the mouth of the bell '2 and thenon-elastic packingljt, a clamping ring or packing engaging ringfi toforce thepacking against the bell, ring 7 to engage the exterior ofthebell and afi'ord an abutment of New York and in Wrought- Metal Ringsfor Pipe-Couplings; and I do to be a full,. the invention,fsuch'aswillenable others skilled in the appertains to make and use I Specificationof Letters Patent.

for bolts 8, which connect the rings 6 and compressed. The greateststrain on the packing engaging ring 6 is obviously in the direction ofthe axis of the ring. The bull ring, however, is not only subjected tothis strain but also to a strain in a direction perpendicular to theaxis of the ring, by reason of-the fact that the bell end acts like ataper plug and tends to enlarge the'pipe opening of the ring.

One of the objects of my invention is to provide a ring which is soformed as to be thoroughly reinforced against both these strains, andwhich can, therefore, be used for either the packing e.accompanyingdrawings I haveembodimentof my invention sepurposes of illustration andseveral modificationsthereof and adapti ed particularly. for use inconnection with engaging ringor the bull ring of such .a clamp, it beingunderstood that the bull ring will of necessity be made with a largerpipe aperture than .the packing engaging ring of the same clamp.

In carrying out my invention, I bend up the inner marginal portions ofnular blank from which the ring erably formed in such manner as to isprefcause It bull ring of which emjoint illustrated 1 plain end ofspigot 3.01 the other to reinforce the described.

The preferred form of v illustrated in Figs. 1', 2 and 3 in which Figs.-1 and 2 show both the packing engaging ring and the bull ring embodyingmy invention. The packing engaging ring shown in Figs. 1 and 2 .at theright and in Fig. 3 is formed preferably from a fiat annular blankofsheet steel, or iron, such.as boiler plate or other sheet metal, andis pressed into shape by the action of suitable dies, or otherwise. Thisring 6 comprises- 7 and enable the packing to be properly the ana ringstructure as hereinafter my invention is an annular plate member 10,provided'with a plurality of bolt holes, ably-a stiffening flange 1 Anannular wall 12 extends from the inner edge of the plate member. 10 andmay be disposed substantially perpendicular to the plane of the platemember or slightly oblique thereto. From the end of said annular wallopposite theend which joins the plate member is an inwardly extendingflange 13 and the inner marginal portions of the blank are bent outwardfrom the inner edge of. flange 13, and backward toward the said annularwall, forming an internal reinforcing flange 14, the outer edge of andhaving prefer:

which preferably engages and "is pressed into contact with the annularwall be- 1 at its outer edge.

tween its ends and preferably adjacent to flange 13 either outwardly,orin the direc- -tion of the axis of the ring will be transmitted to theannular wa-ll and to the plate member by the reinforcing flange .14. Thepipe aperture is formed obviously at the junction of the flanges 13 and14 and the bends 15 and 16 at the inner and outer edges of the flange 13will also 'greatly stiflen the structure of he ring. -When the ring isto be used as the packing engaging ring, the -outer face of the flange 13"w11l'engage the 15 packing, that is to say, the face more remote fromthe plate member, and I prefer to slightly bend or curve the flange 13,annularly' as shown, so that the portion thereof adjacent tothe pipeaperturewill be nearer the plane of the plate member than the part whichis adjacent to the annular wall 12, thus forming an annular bead at thejunction 16 of flange clined OI jCllIF-V'Qd packing engaging faceserving to press-the packing toward. the pipe, as well as toward thebell mouth, but this is not essential, as flange 13 may be disposedsubstantiallypor actually perpendicularly to the axis of the rmg as'shownin-the caseof the bulPring 7.

The bull? ring.7 is formed in the same manner as the ring has shown inFig. 1, the artsbeing given corresponding reference numerals with theaddition of the exponent a, ekeept that the diameter of the pipeaperture is suficiently'larger. than that of the clamping ring, topermit: it to engage the bell and of the joint, and inwardly extendingflange, marked 13 may be straight as shown. In the ease of the ,bull'ring 7 it will be noted that the reinforcing flange v serves anadditional purpose in ing the ring to resist expansion ina 5 caused bythe wedging aetionhof' the bell end.

In the form shown in Fig. 5, the latemember 10 and annular .wall 121are 0 the form previously described-.T-he metal ferming'the inwardly ,extending flange 13 is bent nacurveover back upon said flange, forming the reinforcing flange 1 L, whichhas its outer edge engaging the annu-- lar wall 12 at itsjunetion withflange 13.

.InFig 6 a ring of. thesame general form as that-in-Fig. 5 is shown,except that the 9 reinforcing flange I i is bent sharply back uponandlies flat upon the; inwardly .exv tending flangei 13. InF-ig; '7 theplate member 10 isJprovidedl'witli an annular wall 12 having an angularshape', that is to say being bent-inward so that it forms 5 two portionsunited'centrally to. form an.

angle or shoulder 18", which furtherfstiifens the metal of the saidwell. The inwardly extending flange 13,extendsfr'om the end is bentsharply back upon the flange 13. In F 15:. 8 a form similar tothat shownin'Fig.

"7 is illustrated, .1 -thatthe WalllZ extend-Q ing from the inner edgeof the plate meniber' 10 is bent inwardly.aboiit centrally to n5 formthe annular shoulder 18?, but in this case the reinforcing flangel t.which ex "tends fromthe inner edge of the annular flange 13, extends, inline with that portionof' the" annularwall adjacent to the plate memberand engages the said wallat the -centralshoulder 18, so that any strainupon is transmitted. portions thereof in line witlpthereinforc 1 to theplate member in a straight line. j

in allof the forms herein shown 'and de scribed, it 'willbe' noted thatthe reinforc-I ing flange is formed bybendin g up the inner marginalportions of the annular blank u from the innere'dge of the inwardlyextending flange, and HL all the fo'rmsnshown the outer extremity of thereinforcing flange is brought preferably into contact with theannularfwall either adjacent to or at a. (115'- tance-from it's'qunct onwith' the inwardly 'extveglding flange. I

ileI-p'refer'to form all of the rings so that if the ring is formed froma I to the scrap heap unless fth'e side of said inwardly extendingflange forcing flange 'isformedtifrom the inner marginal portion.of'theblank, and the blank itself is not increased its exterior diameterin providing the metal for said reinforcmg flange and the'blank canbe'cut from a' piece of metal of the same area, as would be employed inmaking'a r ngnot so reinforced.

hls is important from aneconomic'standb point, as the central portion ofthatfpart of a sheet of metal from-which the blank'isfcut, must ofnecessity be cut out, and is relegated it is ofsuch-size that it can beutilized for a blank forsr'naller sizes, and to' do thisusually'requi-res that it be re-rolled to'bring it to the desiredthickness for a smaller ring. In makingthe rings .accordin to myinvention a portion-of this practical y 'Waste material is utilized instrengthening the ring, and as. a thinner sheet can ,be' used for theentire ring than where the ring is not so reinforced, economy ofmanufacture results. a
